Priority Changes

Reports the priority changes that took place for all user tasks in each priority run queue during the sample interval. It is normal to see some priority switching due to system-related activity. For example, such priority switching occurs when:

If you are using logical process management and there are a high number of priority changes compared to steady state values, it may indicate that an application, or a user task related to that application, is changing priorities frequently. Check priority change data for individual applications. Verify that applications and logins are behaving as you expect.

If you determine that a high-priority change rate is not due to an application or to related tasks, then it is likely due to system activity.


Total Priority Changes

Reports the total number of priority changes during the sample period. This section gives you a quick way to determine if there are a high number of run queue priority changes occurring.
